CARPENTERS GAGE.

Specification of Letters Patent.

Patented June 2, 1914.

Application filed March 31, 1913. Serial No. 757,731.

To all whom it may concern Be it known that I, REUBEN M. Baritone, a subject of the King of Great Britain, and resident of Maiden, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements n Carpenters Gages, of which the following is a specification.

My invention consists in a gage to ass st carpenters in accurately fitting doors and the like into the frames prepared for them.

In the present practice, doors which are to be hung in a house are made a little too wide for the frames in which they eventually fit, and in erecting the door frames the sldes thereof are not absolutely accurate, so that each door has to be trimmed and tried before it fits with the proper slight clearance to enable it to be hung in the frame.

The gage which I have invented is designed to make the work of door-fitting easier and to enable the house builder or carpenter to make an accurate fit between a door and its frame more rapidly and with less labor than heretofore.

In the drawings hereto annexed which illustrate my invention, Figure 1 is a slde view of a simple form of gage; Fig. 2 1s a plan view of the same; Fig. 3 is an illustration of the mode in which the gage shown in Figs. 1 and 2 is used in fitting a door to its frame; Fig. 4 is a side view of a preferred and completer form of gage; and Fig. 5 is a side view of one end of the same with its extension piece in extended position.

Referring to Figs. 1 and 2, the main body of the gage consists of an extensible measuring bar composed of sliding members A and B, the member A having an offset A at one end of such proportions that the side of the offset lies in about the same plane with the side of the member B. Metal straps a and b secured respectively to the members A and B, hold the two members in telescopic sliding relation and on one or both of these straps there may be provided a set screw as Z) to set the extensible measuring bar at any point of extension. Securing plates C and D are fastened respectively to the offset A of the member A and to the end of the member B. These extension plates are provided with holes C and D which serve as means for temporarily attaching the gage to a door, this attachment being made by driving small nails or brads through these holes into the door.

The end of each member of the extensible bar'is provided with means for attaching extension pieces E. These extension pieces are preferably of metal and comprise a dowel E which fits with convenient tightness in either of the holes F, G, bored for the purpose in the members A and B. Each extension piece also has a projection E While only one such extension is absolutely necessary, it is preferable to have one for each end of the measuring bar.

The mode of use of the measuring bar shown in Figs. 1 and 2 is illustrated in Fig. 3. The members A and B of the measuring bar are extended until their opposite ends bear against the edges H, H of the door frame H. If the extension pieces E are at this time affixed to the gage, the gage is so applied that these extension pieces will project over the sides of the frame H. The set screw 5 is then turned tight. lVhen the width of the frame at its top has thus been gaged by one such measuring bar, the width at or near the bottom is similarly gaged by another. Then these two measuring bars are taken to the door which is to be made to fit in the frame in question and the measuring bar which gaged the top of the frame is temporarily secured by means of nails or brads driven through the holes C, D, of the plates C, D, in such manner that each of these plates, and therefore the end of the measuring bar, comes slightly inside the edge of the door which is assumed to be somewhat oversize. The spacing or inset from each edge of the door to the end of the measuring bar should be about the same on each side. The measuring bars used respectively to gage the top and bottom of the frame are thus secured to the door at its top and bottom. Then the door is placed against the frame in such manner that the extension pieces E of the top and bottom gage, re spectively, bear with their projections E against one edge of the door frame as H. When the door is in this position a scribing instrument which may be an ordinary pair of adjustable compasses as shown at Y (Fig. is set so that it spans the distance from the edge H. of the frame H to the adjacent end of the extensible measuring bar secured to the door X. Then, using the side of the frame H as a guide, the scribing instrument is drawn down marking just inside of the edge of the door with a line at all points equidistant from the edge E of the frame H. Thus, all irregularities in the frame are reproduced on the line drawn by the scribing instrument Y. When the line has been drawn at one side of the door, the door is shifted sidewise so that the projections E of the extension pieces E at the other side of the door X bear against the edge of the side H of the frame H and the scribing instrument is again employed to mark the door near its edge using the side H of the frame as a guide. The scribing instrument my not arrive exactly at the ends of the measuring bar at the bottom of the door because whichever of the two measuring bars is employed to determine the starting point of the scribing instrument, the other is used simply as a holding device to hold the edge of the door X in approximate parallelism to the side of the frame H.

Referring to Figs. at and 5 which show acompleter and preferred form of gage, A, B, as before, are the two members of an extensible measuring bar, a and Z) the metal straps which hold these members in telescopic sliding relation, and Z) the set screw for securing the two members at any given point of extension. In this construction only one extension piece is used. This comprises a bar 3 which is hinged at w to the measuring bar member 13 so that it may be turned up out of the way when the measuring bar is being used to gage the width of the door frame and may then be turned down into extended position and there secured by means of the catch 7. The clamp 8 is formed as a sleeve or slide upon the extension 3 and is normally urged toward the guide 4 by means of the spring 10; the guide is rigidly secured to the extension 3. A binding screw 11 pivotally secured at 12 to the slide 8 carries a nut 13 which cooperates with the lug 14 in a manner and for a purpose presently to be described. At the end of the member A of the extensible measuring bar there is secured a guide 5 adjacent to which there is a sliding clamp 9 constructed in all respects like the sliding clamp 8 and provided with a binding screw and nut and a spring 10 which draws the clamp 9 toward the guide 5. At the end of member A there is secured a notched projection G and a similar notched projection G is secured to the end of the extension 3. The guides A and 5 are so placed that the distance between their outer edges is the same as the distance between the ends of the measuring bar members A and B no matter to what degree they are extended.

When the measuring gage is used the extension 3 is turned up out of the way as shown in Fig. and the width of the door frame gaged by extending the two members A and 13 until the notched projection G on the bar A rests against one side of the frame and the end of the member B rests against the opposite side. The two members A and B are then clamped together and the extension 3 turned down and latched in place as shown in Fig. 5. The binding screws 11 are turned'out of engagement with their respective lugs and tie gage is then temporarily secured to the door by drawing the clamps 8 and 9 outward and slipping their projections 15 and 16 over opposite edges of the door. The springs 10 hold the measuring gage in place so that the gage can be shifted if need be until the guides i and 5 are spaced substantially equal distances from the adjacent edges of the door, and then the nuts 18 on the binding screws 11 can then be screwed tightly upagainst the lugs 14 so as to hold the gage firmly in place on the door. Two such gages being applied to a door in the manner illustrated in Fig.

3, the door is temporarily placed in the frame with the projections G at one side bearing on the side of the frame. The scribing instrument, as Y, can then be set so as to start the mark from the outer edge of one of the guide plates as 5, the mark scribed near one edge of the door, the door then shifted so as to bring the projections G at the opposite side to bear against the frame, when the guide mark can be scribed near the other edge of the door. When a door has thus been marked it can quickly be trimmed to the lines thus drawn and willthereupon conform to the door frame in spite of the inevitable irregularities in the frame.
